TECHNICAL FIELD

The present invention relates to a novel compound having an antiviral action, in more detail, an anti-HIV drug.

BACKGROUND ART

Among viruses, human immunodeficiency virus (hereinafter abbreviated as HIV) that is a type of retrovirus is known to be a cause of acquired immunodeficiency syndrome (hereinafter abbreviated as AIDS). As a therapeutic agent of the AIDS, reverse transcriptase inhibitors (AZT, 3TC, etc.), protease inhibitors (indinavir, etc.), and integrase inhibitors (raltegravir, etc.) are mainly used so far, but problems of side effects such as kidney problems and emergence of resistant viruses have been found, and development of anti-HIV drugs having a mechanism of action different from those is expected.

In addition, in the treatment of AIDS, because resistant viruses easily emerge, it is reported that, multiple drug therapy is currently effective. As the anti-HIV drugs, three types of reverse transcriptase inhibitors, protease inhibitors and integrase inhibitors have been used clinically, but the agents having the same mechanism of action often exhibit cross-resistance, or merely show additive effects, and there is a demand for the development of anti-HIV drugs having a different mechanism of action.

In Patent Document 1, a compound having a carboxymethyl benzene skeleton as an HIV reverse transcriptase inhibitor has been reported. In addition, as HIV replication inhibitors relatively similar to that of the present invention in structure, carboxymethyl pyridine derivatives (Patent Documents 2 to 8), carboxymethyl pyrimidine derivatives (Patent Documents 9 to 11), phenylacetic acid derivatives (Patent Documents 12 to 13), a tricyclic carboxymethyl pyridine derivative (Patent Document 14), a carboxymethyl pyridone derivative (Patent Document 15), a substituted five-membered ring compound (Patent Document 16), and a substituted six-membered ring compound (Patent Document 17) have been reported.

Patent Document 18 and Non-Patent Document 1 describe compounds relatively similar to that of the present invention in structure, but each document relates to an antiepileptic drug and an analytical technique. Non-Patent Documents 2 to 6 describe compounds relatively similar to that of the present invention in structure, but all the documents relate to antibiotics.

Further, the patent applications for HIV replication inhibitors (Japanese Patent Application No. 2011-146118, Japanese Patent Application No. 2011-176630, Japanese Patent Application No. 2012-095869) have been filed by the applicants.

Experimental Example 5 Solubility Test

The solubility of each compound was determined under 1% DMSO addition conditions. A 10 mmol/L solution of the compound was prepared with DMSO, and 6 μL of the solution was added to 594 μL of an artificial intestinal juice (water and a 118 mL solution of 0.2 mol/L NaOH reagent are added to 250 mL of 0.2 mol/L potassium dihydrogen phosphate reagent to reach 1000 mL) with a pH of 6.8. The mixture is left standing for 16 hours at 25° C., and the mixture is vacuum-filtered. The filtrate is two-fold diluted with methanol/water=1/1 (v/v), and the compound concentration in the filtrate is measured with HPLC or LC/MS/MS by the absolute calibration method.

Experimental Example 6 Fluctuation Ames Test

The mutagenicity of the compound of the present invention was assayed.

20 μL of freezing-stored rat typhoid bacillus (Salmonella typhimurium TA98 strain, TA100 strain) was inoculated on 10 mL of a liquid nutrient medium (2.5% Oxoid nutrient broth No. 2), and this was cultured before shaking at 37° C. for 10 hours. 9 mL of a bacterial solution of the TA98 strain was centrifuged (2000×g, 10 minutes) to remove a culturing solution. The bacteria was suspended in F buffer (K₂HPO₄: 3.5 g/L, KH₂PO₄: 1 g/L, (NH₄)₂SO₄: 1 g/L, trisodium citrate dehydrate: 0.25 g/L, MgSO₄.7H₂O: 0.1 g/L), and the suspension was added to 110 mL of an Exposure medium (Micro F buffer containing Biotin: 8 μg/mL, histidine: 0.2 μg/mL, glucose: 8 mg/mL). The TA100 strain was added to 120 mL of the Exposure medium per 3.16 mL of the bacterial solution to prepare a test bacterial solution. Each 124 of a test substance DMSO solution (several stage dilution from maximum dose 50 mg/mL at 2- to 3-fold ratio), DMSO as a negative control, 50 μg/mL of 4-nitroquinoline-1-oxide DMSO solution for the TA98 strain, 0.25 μg/mL of 2-(2-furyl)-3-(5-nitro-2-furyl)acrylamide DMSO solution for the TA100 strain each under the non-metabolism activating condition, 40 μg/mL of 2-aminoanthracene DMSO solution for the TA98 strain, 20 μg/mL of 2-aminoanthracene DMSO solution for the TA100 strain each under the metabolism activating condition all as a positive control, and 588 μL of the test bacterial solution (a mixed solution of 498 μL of the test bacterial solution and 90 μL of S9 mix under the metabolism activating condition) were mixed, and this was shaking-cultured at 37° C. for 90 minutes. 460 μL of the bacterial solution exposed to the test substance was mixed with 2300 μL of an Indicator medium (Micro F buffer containing biotin: 8 μg/mL, histidine 0.2 μg/mL, glucose: 8 mg/mL, Bromo Cresol Purple: 37.5 μg/mL), each 50 μL was dispensed into microplate 48 wells/dose, and this was subjected to stationary culturing at 37° C. for 3 days. Since a well containing a bacterium which has obtained the proliferation ability by mutation of an amino acid (histidine) synthesizing enzyme gene turns from purple to yellow due to a pH change, the bacterium proliferation well which has turned to yellow in 48 wells per dose is counted, and was assessed by comparing with a negative control group. (−) means that mutagenicity is negative and (+) is positive.

As a result, the mutagenicity of compound I-6, I-11, I-12, and II-3 was negative.
